Blade Spotlight: Part 1

Quality Industrial Blades Explained

Carolina Knife Co. provides the highest quality industrial knives and cutting tools to manufacturers all over the world! But what exactly are our knives made of? What is each blade used for? We’d like to take some time to provide a brief overview of the types of resources that we offer at Carolina Knife Co. so that your questions can be answered! If there are any topics that we don’t cover in this article, please do not hesitate to call one of our professionals, and we can give you an expert answer! We hope this can be a helpful introductory resource to the products and services we offer. We are ready and able to provide you and your business with the cutting tools that you need to get your projects done!

Carbide Knives

Our carbide knives are made from a chemical compound called “tungsten carbide.” As you might guess, this is a combination of tungsten and carbide atoms. In its most basic state, tungsten carbide is a powder, but through a process called “sintering,” this powder is compressed and shaped with heat and pressure, without reaching the liquifying point. The resulting material is extremely hard, and is resistant to both heat and warping. This is a common material used for jewelry for this very reason. 

Cutting tools that are composed of tungsten carbide are able to withstand much more activity than standard steel blades, typically surviving up to 50 times longer. However, tungsten carbide is susceptible to chipping and breaking, just like any other metal. Because of this fact, it is not uncommon for blades to be tungsten carbide tipped, rather than composed completely of the material. Regardless of blades being tipped or entirely made of tungsten carbide, they are an above-industry standard when it comes to durability and resistance to wear. 

Common applications for tungsten carbide blades include woodworkers and craftsmen. The precision that is provided by this strong material allows for excellence in furniture crafting. These blades are ideal for detail work, as well as food service slicing, and paper slicing. You can shop our selection of tungsten carbide products here.

Circular Blades

When it comes to circular industrial blades, Carolina Knife Co. utilizes several different materials based on the function of the circular blade in question. We’ll go over some of the practical uses for circular blades first, then provide a brief description of the different materials we use to create them.

Circular blades provide a continuous cut for processes like the following:

  • Paper conversion, the process by which manufacturers cut, shape, and roll paper products.
  • Film and foil conversion, the process manufacturers use to cut thin metallic or plastic-based products into shapes, such as plastic cling wrap or tin foil.
  • Textile processing, where fabrics or similar materials are cut and shaped from large swatches.
  • Tire and rubber manufacturing, where manufacturers are able to cut and shape rubber that will be processed into household and automotive items, among other needs.

The previous list is far from exhaustive, but it should give you a general idea of the practical applications that circular blades are used for. We’ll now give you a brief description of the different blade materials we use to create the highest quality products on the market.


  • M2- This is a high-speed steel that is very tough, and is composed mostly of tungsten, molybdenum (an element highly resistant to corrosion), and chromium (a common additive to steel that further resists corrosion.) This metal is tough, wear-resistant, and tends to keep its sharp edges longer.  
  • 52100 Tool Steel- This particular steel contains high levels of carbon, making it extremely hard and able to cut a wide variety of materials. However, because it has low levels of chromium, it is susceptible to corrosion. Our experts at Carolina Knife Co. can help you determine if this extremely hard steel is right for your operation.
  • D2- This steel is air-hardened contains high levels of carbon and, unlike 52100 steel, high levels of chromium. The level of chromium makes this steel almost appear to be stainless steel. Because of the high levels of carbon and chromium, D2 blades are ideal for work that takes place in cold conditions, being able to avoid most abrasion. This steel also contains amounts of molybdenum and vanadium, which helps to prevent oxidation of the steel.

Hot Cut Products

Hot cutting tools differ from traditional blades in that they primarily depend on high levels of heat to be useful to manufacturers. Trades that regularly make use of hot cutting knives include textile manufacturers and other manufacturers that require the simultaneous action of cutting and sealing products. Our hot cutting units are comprised of a hot cutting knife that is heated up to 1500 degrees Fahrenheit, and a holding unit for the heating element.

Carolina Knife Co. is proud to provide top-of-the-line hot cutting tools, including hot cutting blades, hot cutting knife holders, and hot cutting knife carriers, as well as entire kits for ease and convenience. Shop these tools right here, and bring us any further questions you may have about product safety, operation, and practical usage in the manufacturing process.
